    The one thing the Argentines never under estimated was the RN SSN’s, what they under estimated was the British being prepared to go to war over islands that most in this country knew nothing about and cared even less about. The Argentine commander of submarines was directly asked whether his boats could counter RN SSN’s in a slightly earlier crises and his negative response was an important reason for them not risking a war at that point. Lets face it, if the government had been in a position to get a couple of companies of infantry down there in a hurry it would probably have been enough to deter the invasion as it would have signalled that we were prepared to fight.

    The outside chance is that the RAAF may procure some of the STOVL examples of the Lightning II for operations of the new Canberra class amphibs. Said operations being undertaken at some significant detriment to the Canberra’s principal designed function, which is to embark large numbers of helicopters and troops for amphibious operations.

    A good point and one of the main misconceptions of how many view these type designs. Many view the newer generation of LPH/LHD as a cheap CVL with the added bonus of an amphibious capability, when actually they’re amphibious assault ships that can be made to operate STOVL fighters if required at the expense of their primary function in most cases. Ships like the Juan Carlos, Canberra, Ocean etc. are excellent assault platforms, but they’re not USN style LPH’s that can operate Harriers and in the future F35B’s at the same time as fulfilling their primary role as assault vessels, and most operators of the type don’t even pretend it can be done. This isn’t an attack on the ships as I’m a huge fan of the vessels, but they have to be viewed as what they are, not what people might wish they are. Similar to the CVF, the RN has aimed at what they can realistically achieve and accepted a far more conservative ship than a USN CV, OK I’m sure they’d love a USN style CV but it’s beyond their means and capabilities and so they’d gone for something that does meet their needs and is (only just) affordable to build, operate and support.

    The RAN hardly has the manpower or budget for three Aegis Destroyers. Let alone a Super Carrier the size of the CVF or Nimtz Class.

    I quite agree, my comment was aimed more at the suggestion of a country buying or leasing an ex-USN CVN, and even if the USN gave them away for free (perhaps as a way of keeping the hulls active to relieve pressure on USN carriers, the basic idea behind that suggestion of transferring JFK to NATO) they’d still be prohibitively expensive for any other navy. If the RAN want maritime air power then a F35B on their new LHD’s is the only realistic choice. The RN would almost certainly see a far heavier drain on resources to try and operate a USN CVN even if they got it for free than they’ll ever have to pay into the CVF program over the life of the vessels.

    They went through this with that idea floated of giving away the JFK to NATO, even if the USN gives away one of their carriers for free there is no other navy on the planet they’d consider giving them to with the resources to operate them, given the crew requirements and cost of air ops on that sort of scale, and if it’s a nuke the problems are even greater. Nice idea, but it’d probably make a lot more sense for Australia to spend $3-4Billion on a new build ship like CVF or PA2 than accept a USN CVN, daft as that may sound.

    Ocean wasn’t designed as an aircraft carrier, she was designed as an affordable (read cheap) Commando Helicopter carrier and her deck layout and systems were optimised for the dual purpose of carrying a marine embarked force and keeping costs down, and on the whole she has been pretty successful on both counts. The RN took the not unreasonable view that with three CVL’s they could afford to build a dedicated assault platform. If they really wanted to I’m sure Ocean could be re-fitted to carry fighters, she can already ferry Harriers, but it’d be at the expense of her primary mission as an assault ship, which would render her whole reason for existing as pointless, and why lose a valuable asset to turn her into a much slower and less capable version of an Invincible when the RN still have two perfectly good Invincibles with a third still there for emergencies until they finally decide to either sell her or send her to the breakers? An assault ship is a valuable asset in it’s own right, one of the major problems faced by the RN in 1982 was that Hermes served as a carrier rather than a Commando carrier making the landing forces job an awful lot harder. Since the Ocean’s basic hull was derived from the Invincible hull form many have decided she is just a cheap Invincible with diesels and that is nowhere near the truth, aside from the basic hull there is virtually no similarity with the Invincible class, no more so than between a Leander and Type 22 which share a similar link in basic hull forms. Ultimately there is so much a ship can do in a certain size, the space required to operate Harriers or F35B’s, stores, munitions, engineering support, hangar facilities etc. has to be at the expense of helicopters and their equipment, stores for the embarked force etc. meaning the assault function is heavily restricted for the purpose of carrying fighters. If there is no alternative then it may be Hobsons choice, but it is not the choice you’d make if there was an alternative. There is also a question of basic hull form, the hull demands of a carrier and an assault ship with a floodable dock or even just straight Ro-Ro type decks with side and stern ramps are very different and put very different demands on a designer. Yes, it is possible to do it and make a ship that can carry a squadron of fighters and an embarked marine force and helicopters at the same time and do both jobs well, but not for the price or size of an Ocean or Juan Carlos.

    Fitted for but not with is not an idea I especially like but when there is only so much money in the pot it is probably the least bad compromise IMO. The RN are getting a superb AAW destroyer with good growth potential, a ship fully capable of filling it’s primary role of AAW at the expense of secondary land attack and ASuW capabilities seems preferable to cutting corners on her AAW systems to free up funds for other roles or even bigger cuts in hull numbers. But that’s just my view, I know others differ.

    A cynic might say the usual means of avoiding this little problem is to give technology to Israel and stipulate they’re not allowed to sell it on to the countries in question. So France just needs to sell Aster to Israel but make sure Israel knows that on no account must they give it to Taiwan and in 5 minutes them Lafayettes will be fitted with Aster:diablo:

    Fitting TLAM wouldn’t be a two minute job, but the hull is already configured to take the strike length Mk.41 VLS for 16 cells or an enlarged Sylver if they want more Aster missiles or a navalised Storm Shadow. Fitting Harpoon would be the equivalent of a two minute job and wouldn’t even need a full dockyard, it could be done alongside almost any quay.

    The RN originally accepted a lot of “fitted for but not with” in order to get 12 hulls, then it was cut to 8 and they may end up with 6, a far cry from the famous the navy wanted 6, the treasury offered 4 and they compromised on 8 row over battleships before WW1. Makes me wonder what the RN would have pushed for 10 years ago if they’d known the government would fail to honour their part of the bargain, was a bit naive of the RN ever to swallow that whole cuts now for jam tomorrow BS IMO.

    Can they operate the F35B simultaneously with operating as amphibious assault ships though? This is the problem, the small STOVL carriers can operate as effective carriers, or they can operate as good commando carriers, but to operate as an effective STOVL carrier whilst landing a marine battalion and meeting their logistics needs is a lot harder. I think that’s what Swerve was meaning, although I may be wrong. To have a truly dual purpose ship that is effective and efficient in both roles is an awful lot harder (read more expensive) than making a ship that can be quickly re-configured between the two roles. The Ocean probably could carry STOVL fighters if they really wanted her to, but it’d be at the expense of her primary role of carrying a marine group and landing/supporting them.

    As well as manpower there is the provision of air groups, and they’re anything but cheap, whether CTOL, STOVL, STOBAR or purely rotary. And the LPH/LPD has a reputation as a cheap type based on the fact that most of them are built to commercial methods with economical diesels, lean manning and in many cases very limited C&C and sensor suites. If you put in fleet command facilities and a genuinely front line capable sensor suite, high power engines for high speed manouvering (probably, but not neccessarily gas turbines), build to fully military standards etc. they’re no longer the bargain that their cheaper brothers are. And since the CVF program needs at least some degree of speed and military functionality then a LPHD candidate would be much closer to the USN vessels of this type than an Ocean, and they’re probably not much different in price to the CVF anyway.

    No, Ocean has a very different internal layout to the CVL’s with decks configured for an embarked marine group and their equipment, and although her basic hull was based on the CVL that is as close as they get, in every other way they’re totally different. That is like saying a Type 22 is just the same as a Leander class with gas turbines instead of steam turbines as the Type 22 hull form evolved from the Leander.

    Interesting, sorry I can’t help with your request but judging from when the images were produced they can’t have been more than very early stage outline concept proposals, but that’s just my guess. Certainly, in the early stages there was a lot of talk of a vessel design seeming much closer to the Italian Cavour than what became the CVF.

    In the long term Ark Royal won’t serve long as a LPH commando carrier IMO, she is too expensive, heavy crew complement and expensive engines and her internal layout seems less than ideal. Her one big advantage over Ocean is speed, but since the rest of the ARG vessels are sub 20kts even this is of limited value unless operating alone as an amphib. They really want another Ocean or similar, cheap to build, cheap to operate and purpose built for the role with excellent internal layout for the embarked group. The newer style commercial build style LPH/LPD types offer an awful lot for little outlay and few if any ships can offer as much capability for such modest outlay, probably the reason they’re so popular.
    On the CVF as commando carrier, it is a secondary role but an important one if they actually have to operate in that mode in anger, but I’m guessing the RN will push for another economical LPH as soon as they can.

    The CVF is certainly about power projection, but it is not a USN CVN and it is not intended to be. The RN can not afford to build or operate carriers in the style of those, whether the CVF is STOVL or CTOL it will lack the logistics infrastructure, naval support assets, air support assets and the financial coffers needed to support a USN style carrier doctrine. We have a saying over here that you can only urinate with the penis you’ve got, and the RN are doing this. Whether the CVF is CTOL or STOVL will not affect the fact they have far less ambitious plans and roles than a CVN, really it is no dumb generalisation to say it really is more like a Invincible or Cavour pumped up on steroids than a CVN. And if you look at RN air ops and what they’ve spoken of in public about the CVN it does actually seem a lot closer to the USMC than the USN. Which is a realistic evaluation of their abilities to afford and support carrier aviation IMO.
